2. Select .003" (.08 mm) shim thickness from the 54529 Shim Pack and install these into the 01478 Front Bearing Plate.

3. Install the 02649 Bearing into the front bearing plate.

4. Use the RAISED CENTER area of the 96240 Bearing Press Tool and the arbor press to install the 02649 Bearing with the bearing plate onto the rotor.

5. Use a .001" (0.3 mm) thick feeler gauge to check the clearance between the bearing plate and the face of the rotor.

6. Clearance should be .001"-.0015" (0.3-0.4 mm). Note: If the clearance needs adjustment, repeat steps 2-6. Add or remove shims as required.

7. Use Dynabrade Air Lube 95842 (10W/NR or equivalent) to lubricate the 01480 Vanes. Install the vanes into the rotor.

Install the 01476 Cylinder and the 02673 Rear Bearing Plate so that the air inlet openings line up with each other.

8. Position the 02696 Bearing onto the bearing journal of the rotor.

9. Use the RAISED CENTER area of the 96242 Bearing Press Tool and the arbor press to install the 02696 Bearing onto the rotor and into the 02673 Rear Bearing Plate. IMPORTANT:

Carefully press the bearing onto the rotor and into the plate until the plate just touches the cylinder. This will establish a snug fit between the bearing plates and the cylinder.

10. Carefully secure the pinion in a vise with aluminum or bronze jaws so that the back end of the rotor is pointing up. Apply a small amount of the Loctite #222 (or equivalent) to

the threads of the governor. Use a torque wrench to install the governor. LEFT HAND THREAD: Turn clockwise. (Torque to 0.5 – 0.9 N•m/4 – 8 in. lbs.) Note: The governor

assembly is not serviceable. If the governor fails it must be replaced as a complete assembly.

11. Install the filter onto the filter cage, and install these into the housing.

12. Carefully slide the motor assembly into the housing.

Motor Assembly Complete.

Planetary Gear Assembly

1. Use the RAISED CENTER of the 96239 Bearing Press Tool and the arbor press to install the 54520 Bearing onto the front of the 50787 Planetary Carrier.

2. Apply a small amount of Loctite #271 (or equivalent) to the threads of the 50782 Adapter or the 53150 Pinion that connect to the planetary carrier. Install these into the

planetary carrier(s). (Torque to 17 N•m/150 in. lbs.)

3. Apply the 95542 Grease (or equivalent) to the bearings in the planetary gears. Install the planetary gears into the carrier(s) and install the 54472 Pins. Install the 54468 Ring

Gear(s) so that the notches will align with the lubricant and setscrew access holes in the 53152 Adapter or 53153 Planetary Housing.

4. Use the RAISED CENTER of the 96239 Bearing Press Tool and the arbor press to install the REAR 54520 Bearing onto the 50787 Planetary Carrier(s). IMPORTANT:

Carefully press the bearing down until it just touches the ring gear. This will establish a snug fit between the bearings and the ring gear.

5. Install the speed reduction gear assembly(ies) into the adapter or planetary housing. Apply Loctite #567 (or equivalent) to the 50784 Setscrew(s) and install to secure the

gear assembly(ies). Note: For Model 47200, install the beveled side of the 50778 Spacer to face the outboard gear assembly and the flat side to face the second gear

assembly. Use the 95541 Lubricant Gun to supply 2 plunges of the 95542 Gear Grease (or equivalent) through the lubricant fitting(s). It is recommended to supply 2 plunges

of grease after every 50-hour interval of use.

6. Apply Loctite #567 to the joining threads of the adapter, rear exhaust cover and planetary housing. Use the 50971 Lock Ring Tool and an adjustable wrench to fasten the

53152 Adapter to the rear exhaust cover or planetary housing. Turn clockwise. (Torque to 28 N•m/250 in. lbs.)

Planetary Gear Assembly Complete.

Final Tool Assembly

1. Insert the "Tear-Drop End" of the 96402 Special Repair Tool into the air inlet of the housing. Place the hex end of the special repair tool in a vise with aluminum or bronze

jaws so that the housing is pointing up.

2. Apply Loctite #567 to the joining threads of the adapter and the motor housing.

3. Use a 34 mm crowfoot and torque wrench or an adjustable wrench to install the 53152 Adapter onto the motor housing. Turn clockwise. (Torque to 28 N•m/250 in. lbs.)

4. Refer to the exploded view for the order of assembly to install the valve and muffler components. Follow adhesive and torque specifications.

Final Tool Assembly Complete.

Motor Assembly Complete. Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.

Important: Before operating, place 2-3 drops of Dynabrade Air Lube (P/N 95842) directly into air inlet with throttle lever depressed. Operate tool for 30 seconds to determine if tool

is operating properly and to allow lubricating oils to properly penetrate motor. Motor should now be tested for proper operation at 90 PSIG. If motor does not operate properly or

operates at a higher RPM than marked on the tool, the tool should be serviced to correct the cause before use.
